FlLTERlNG-FAUCETQ SPECIFICATION forming part of Letters Patent No. 270,881, dated January 23, 1883.

Application filed June 17, 1882.

To all whom it may concern Be it known that I, JAMES ABORN, of the city and county of Providence, and State of Rhode Island, have invented certain new'and useful Improvements in Filtering-Faucets; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of the several features of my invention.

Although my said improvements are of I special value in reversible filtering-faucets,

and are shown and described in that connection, certain portions thereof are applicable glith good results to such as are non-reversi- Numerous reversible filtering-faucets have heretofore been devised. In some cases the filtering-chambers have been rotative for obtaining a reversal of the water-current, and others have been stationary, but so combined with cock-plugs of peculiar construction that by a change in their position the flow of water could be reversed in its passage through the chamber. In some cases the plug itself has contained the filtering-chamber, and in others said chamber has been attached to a shell rotative upon a stationary plug. It is obvious that filtering-chambers constituting a portion of a faucet must of necessity be of comparatively limited dimensions, and that simplicity and economy in construction are matters of material consequence in the practical production of devices of this kind. a

In the development of my invention I have sought to obtain a filtering capacity in any faucet filtering-chamber which will be the maximum capacity of such chamber in each case, and to so construct and organize the various portions of the faucet as to secure effective op eration as well as simplicity and substantial economy.

After a full description of several faucets embodying more or less of my improvements, the features deemed novel will be specified in detail in the several clauses of claim hereunto annexed.

Referring to the drawings, Figure 1 is a side view of a faucet embodying the several features of my invention. Fig. 2 is a longitudinal verticalsection of the same. Fig. 3 is a horizontal section of same on line 0:. Fig. 4 is a (No model.)

side view of another faucet embodying the main features of my invention. Fig. 5 is alon- .gitndinal vertical section of the faucet, Fig. 4. Figs. 6 and 7 illustrate the same reversible filtering-chamber as combined by me with a plug which is rotated independently of said chamber. Fig. 8 illustrates the same reversible filtering-chamber as employed by me with a faucet-plug of the simplest variety.

As shown in Figs. 1 to 3, inclusive, the fancet-body A is precisely as heretofore, having the usual plug-chamber, a, for the reception of a conical plug, the tapered shank b for union with a. water-pipe, and the downwardly-projectin g discharge-nozzle c. This particular form of faucet-body is not essential, and numerous variations may be made therein without in any manner afieeting my invention, a

'will be hereinafter indicated.

The faucet-plugB is conical in form for properly occupying the plug-chamber a, and it is provided with the usual threaded foot, d, nut e, and washerj, whereby said plug may be drawn longitudinally into the plug-chamber for maintaining water-tigh t relations therewith and compensating for wear from time to time. This rotative plugishollow, has a longitudinal central diaphragm or partition, g, throughout its length, and open ports h on opposite sides of the plug and at right angles to said partition. The head of the plug is enlarged, as shown, and affords an annular seat, 2', upon or to which my filtering-chamber is attached. Within said seat is a gauze strainer, k, which rests upon or is attached centrally to the top of the central plug-partition, 9.. The neck of.

The filtering-chamber C may be-of any desired size or form; but I prefer the elongated globular or pear-shaped form, as shown in Figs. 1 and 2. The chamber is provided with a longitudinal central partition, m, which extends from its neck to within a short distance of its opposite end, affording a water-passage, as at n. This chamber may be arranged to. stand pended below it; or it may project laterally therefrom in any desired direction without affectingits proper operation. As seen in Figs. 1 and 2, the chamber is mounted vertically upon the seat 3 at the top of the plug B, and a flexible washer, 0, having a central or diametrical portion, 0, is so interposed as to afford an annular packing for the neck of the chamber, and a cross-packing between the adjacent end of the partition on and the coincident surface of the upper end of the plug-partition g. The plug and chamber are united by means of a threaded ring, 1), having a flange which engages with the plug below the annular seat i, and a screw-thread which engages with the screw-thread upon the exterior of the neck of the chamber. The entireinterior portion of the chamber is first filled with boneblack or other suitable filtering material suitably packed, and the plug is then connected therewith.

As thus far described, it will be-seen that when the plug is in position the quarter-rotation of the chamber will so rotate the plug as to cut offand let on the water, and that a halfrotation of chamber and plug will cause a complete reversal of the filtering-chamber, thus providing .for the desirable self-clearing capacity.

Although the faucet may be operated by grasping the chamber with the hand, I prefer a special handle, and I have shown two ways of applying the same.

In Figs. 1 to 3, inclusive, the handle D is loosely mounted on the neck of the plug, and is provided with a pawl, q, backed by a spring for causing said pawl to readily engage with either of the four ratchet-teeth l on the neck of the plug, so that with each swinging movement of the handle the plug and chamber will be rotated one-fourth of a revolution, but always in the same direction, thus alternately letting on and cutting off the water, accompanied by an alternate reversal of the filteringchamber.

, In Figs. 4 and 5 I show the filtering-chamber globular in form, having the same central partition, m, and water-passage a as before described, and it is secured in the same manner to theplug; but the latter has an extended stem, d, provided with a finger-piece or handle, 0", which, when parallel with the body portion A of the faucet, will permit the water to flow, and when placed crosswise .will cut off the water, as is common with cocks of ordinary construction.

If desired, the inner end of the partition m may be provided with a number of holes or perforations instead of the single larger opening, which I prefer.

In order that such a faucet may be used in a variety of positions and in numerous modes of attachment, I provide the faucet-body A with an internal screw-thread forseparable connection with the tapered shank b or with the screw-nozzle of a separate faucet, and with discharge nozzle 0, which may be curved or straight; or, if desired, no separate nozzle need be used.

It will be seen that with my partitional chamber the water passing through on either side of the partition is tiltrated through a mass of filtering matter, which in thickness is equivalent to twice the length of the chamber, which, so far as my knowledge extends, isnot the case with the chamber of any pre-existing filtering-faucet, whether {of the re\ ersib the non-reversible variety.

I am aware that the chamber may be nonrotative and nevertheless be rendered practically reversible by employing therewith a plug constructed as heretofore in filtering-faucets, so that the entering water can be conducted to either side of the partition in the filteringchamber, and drawn from the opposite side thereof; or, if desired, the plug'may also be so constructed and arranged as to allow, as in other kinds of filtering-faucets, the direct passage of water without filtration, and Ido not therefore limit myself, except as hereinafter indicated, to the rotating filtering-chamber.

I have illustrated in Figs. 6 and 7 a faucet having a rotating plug, and the same filteringchamber so combined therewith that the latter may be reversed, when occasion requires, by slightly loosening the annular nut 12, turning the filter half around upon its seat, and then tightening it up for use until another reversal is desirable. This plug B has a central partition, 9; but instead of being located longitudinally therein it is slightly inclined to the axis of the plug, and laterally divides the interior thereof into two chambers, so that water always enters at the same side of said partition and has its exit from the opposite side.

In the forms of faucet thus far shown and described my filtering-chamber is employed with a plug internally provided with either a longitudinal or crosswise partition; but said chamber may also be employed with a plug of the simplest form, as illustrated in Fig. '8, wherein the body of the faucet in front of the plug B is provided with a central crosswise partition, m, and a flanged neck, to which the filtering-chamber is applied, substantially as already described, so that when a reversal is desired the chamber is loosened in its seat, turned half around, and then tightened. When thus constructed the annular ringp is applied to the flanged neck by the compression of the flanged portion of the ring, after the wellknown manner of attaching swivel-rings in hose-couplings.

It will be seen that I obviate interior waterspaces in my chamber, and also the expense of separately-constructed filtering-compartments within the chamber, also that my chamber can be easily detached and applied to the faucet, and that the filtering-matter is readily packed, removed, and repacked, and that the entire interior portion of the chamber, except that occupied by the thin partition, may be utilized for the reception of filtering-matter,

which, because of said partition, affords a 511- discharged from opposite sides of said partitering mass equal in thickness to twice the length, height, or depth of the filtering-chamber; and it is-also obvious that my faucet in either of the forms shown may be cheaply constructed.

I am of course aware that it is not new to provide cisterns or filtering vats with diaphragms or partitions which secure an extended circulation of water through the filtering-matter; but, so far as my knowledge extends, I am the first to apply that principle to chambers contrived for use in filtering-faucets, with or without the reversible capacity.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- The combination, substantially as hereinbefore described, of a faucet-body, a suitable plug, and a filtering-chamber containing filtering-matter, and provided with an interior central partition extending from the neck of the chamber adjacent to the faucet-body to near the opposite end of said chamber, and with a Water-passage adjacent to the inner end of said partition, as set forth, whereby water flowing through the faucet may be introduced and tion.

2. The combination,substantially as hereinbefore described, of a faucet-body, a suitable o plug, and a filtering-chamber provided with a central partition extending. from the neck of said chamber to near its opposite end, and with a water'passagc at or near the inner end of said partition and rotatively mounted with 35 relation to the faucet-body, whereby said chamber may be reversed, as set forth.

3. The combination of the faucet-body, the rotative pluglongitudinally divided internally, and the filtering-chamber, provided with the 40 central partition and mounted upon said plug, substantially as described.

4. The combination of the faucet-body, the filtering-chamber, the rotating plug carryiug' said chamber, the ratchet-teeth on said plug, 4 5 and the handle provided with the pawl, substantially as described.
